Selection criteria of diluents of tri-n-butyl phosphate for recovering neodymium(III) from nitrate solutions

Abstract

Selection of diluents considering extraction, cost, safety and biodegradability criteria

Molecular-scale understanding of diluent effects on ligand assembly for metal ion separations

“…26 While aliphatic diluents typically enable significantly better extraction than aromatic solvents, studies by Regadı ´o et al found that mixed diluents with both aliphatic and aromatic components performed only slightly worse than the pure aliphatic mixtures. 27 This suggests that diluent effects are complex and nonlinear, indicating that empirical approaches such as solubility parameters derived from mixing rules 28 are not sufficient to capture actual behavior. Poirot et al examined solvent effects from the perspective of solvent structuring and the resultant effect on energetics.…”
